How
can you check if light shows wave properties? If light is a wave,
it should bend around corners; it is not immediately apparent that
light does bend around corners in the same way sound or water waves
do. This model helps demonstrate that light does have these properties.

Can
light waves interact to produce regions of darkness? Waveforms show
destructive as well as constructive interference. This model demonstrates
that light from more than one source can interact to produce regions
of darkness.
